The rainwater reclaiming and filtering device utilizes the principle of centrifugal force, saves energy, filtered impurities can be automatically flushed out, and cleaning labor can be saved.

Description

Rainwater recycling filter

technical field

The utility model relates to a rainwater recovery device.

Background technique

In today's society, water resources are increasingly scarce, and industrial agriculture and residential water use are becoming increasingly tense. For countries like my country with low per capita water resources, it is imperative to save water.

Building roofs are generally provided with drainage pipes at present, and rainwater is directly discharged into the sewer by the drainage pipes. The loss of natural rainwater resources is a pity.

At present, the existing rainwater recovery equipment generally adopts filter screen to filter to obtain relatively clean rainwater. If the filter screen is clogged, it is inconvenient to manually clean it, or use high-pressure water to clean it, which wastes power resources.

Contents of the invention

In order to overcome the above disadvantages, the utility model provides a rainwater recovery device which utilizes the principle of centrifugal force to filter impurities.

The technical scheme of the utility model is: a rainwater recovery and filtering device, the main body is an upright tubular container, the upper part of the container is provided with a horizontal water inlet pipe, the lower part of the container is provided with a horizontal water outlet pipe, the bottom of the container is provided with a waste water discharge pipe, and the container cavity is arranged along the inner wall. There is a tubular filter screen, a clean water chamber is formed between the inner wall of the container and the filter screen, the clean water chamber is connected to the outlet pipe, the rainwater chamber inside the tubular filter screen is connected to the waste water discharge pipe, and the clean water chamber and the rainwater chamber are closed.

The water inlet pipe of the utility model is a horizontal pipe, adopts the design method of forming flow velocity and centrifugal force, and utilizes the principle of centrifugal force, the rainwater enters the container cavity through the horizontal water inlet pipe and rotates; Due to the surface tension of water and the physical characteristics of automatic welt, the clean rainwater falls to the vertical surface of the clean water chamber and is collected through the outlet pipe; using the principle of gravity, impurities in the rainwater and excess rainwater fall and are discharged through the waste water discharge pipe , keeping the cleanliness inside the utility model.

Detailed ways

In order to further understand the content of the utility model and highlight its structural advantages, the specific implementation modes are described in detail as follows with reference to the accompanying drawings.

As shown in Figure 1, the rainwater recovery filter device has a plastic container 1 as its main material, a cover 3 on the top of the container, a horizontal water inlet pipe 2 on the upper part of the container, a horizontal water outlet pipe 4 on the lower part of the container, and a horizontal water inlet pipe. Both 2 and the horizontal outlet pipe 3 can be rotated 360 degrees. The horizontal water inlet pipe and the horizontal outlet pipe are connected to the container by grooves interlocking with each other so as not to come out. The grooves are provided with rubber leak-proof grooves to prevent rainwater from leaking out.

The horizontal water inlet pipe 2 for the rainwater to enter, the horizontal water outlet pipe 4 for the purified water to be discharged after filtration, and the waste water discharge pipe 5 for the sewage at the bottom are three pipes in total, and the rainwater recovery and filtration device body can be rotated 360 degrees individually to facilitate piping. Save space, achieve the goal of low overall equipment cost, money saving and short recovery time. The plastic integral molding structure between each pipe and the device body can form a closed circumferential fastening structure with the body. Using the technology of thermal expansion and contraction of plastic pipes, they are fastened to each other. There is a space for leak-proof rubber rings in the middle, coated with Minimal amount of lubricating oil ensures smooth running at slow speeds. When piping, you can turn each pipe at one time according to the direction required, and fix the piping. The loss of lubricating oil in the future will not affect the sealing performance.

A tubular filter screen 6 made of stainless steel is arranged in the inner cavity of the middle part of the container 1. The mesh length of the filter screen 6 is 0.1-0.8 mm. The mesh length can be set according to regional differences and uses. The space between the inner wall of the container and the filter screen It is the water purification chamber 7, which is directly connected to the horizontal outlet pipe 4, and the cavity inside the tubular filter is the rainwater chamber 8, which is closed between the rainwater chamber 8 and the water purification chamber 7, and the rainwater chamber 8 is directly connected to the set Wastewater discharge pipe 5 at the bottom of the container.

The utility model can also be provided with a support point on the side, which is convenient for setting a bracket to be fixed on the wall, and the utility model can also be installed underground for use.
